SOLAR SYSTEM

Detailed explanation-1: -As the nebula collapsed under its own gravity, it spun faster and flattened into a disk. Most of the nebula’s material was pulled toward the center to form our Sun, which accounts for 99.8% of our solar system’s mass. Much of the remaining material formed the planets and other objects that now orbit the Sun.

Detailed explanation-2: -Our entire solar system also has a barycenter. The sun, Earth, and all of the planets in the solar system orbit around this barycenter. It is the center of mass of every object in the solar system combined.

Detailed explanation-3: -The material in the nebula not absorbed into the Sun swirled around it into a flat disk of dust and gas, held in orbit by the Sun’s gravity. This disk is called an accretion disk.

Detailed explanation-4: -Gravitational collapse Before it was moulded into a neat set of planets, every scrap of matter in the solar system was part of a gigantic nebula-a floating interstellar cloud. This giant cloud was made up of dust, hydrogen, and other gases. It began to collapse in on itself after becoming gravitationally unstable.

Detailed explanation-5: -A star, which is called the sun, formed. The sun is composed of about 99% of all the matter that was contained in the solar nebula.
